Overview

Microsoft Graph API is a unified gateway to data across Microsoft 365, including emails, calendars, files, and Teams messages. It uses OAuth 2.0 for authentication and returns JSON data, making it the standard way to integrate with Microsoft services. Beginners should start with the Graph Explorer at developer.microsoft.com to test calls without writing code.

Beginner Tip

Use the Microsoft Graph Explorer (graph.microsoft.com/graph-explorer) to run live API calls with your own account — it handles authentication for you and shows you exactly what data you get back.

Available Data

The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.

Example Response

Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

JSON Response · Illustrative

Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

Request

const url = "https://docs.microsoft.com/en-us/graph/api/overview";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "Authorization": "Bearer YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

401 Unauthorized Access token is missing, expired, or lacks the required permission scope

✓ Re-authenticate to get a fresh token and ensure your app registration includes the necessary Graph API permissions (e.g., User.Read)

403 Forbidden The token is valid but the app or user does not have the required permission

✓ Add the missing permission scope in your Azure AD app registration and re-consent

404 Not Found The resource ID in the URL does not exist or you are using the wrong API version

✓ Double-check the user ID, group ID, or file ID; try switching between /v1.0/ and /beta/ endpoints

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
